I'm using the example code here: http://www.hdfgroup.org/ftp/HDF5/examples/parallel/Hyperslab_by_row.c
When I run this code with 8 processes on separate nodes, it works fine. When I run this code with 8 processes on the same node (ppn=8), it works fine. When I run this code on 2 nodes with 4 processes per node (ppn=4), I get a segmentation fault in H5Fcreate. Any help or guidance would be much appreciated.
